SAN ANGELO, Texas (AP) Federal authorities say a Mexican Mafia gang that's been trafficking methamphetamine in two West Texas cities since 2004 has been dismantled.

Six people were arrested Wednesday morning in San Angelo and eight were already in state custody on related charges, a release from the U.S. Attorney's Office states. One man is still being sought.

The 15 are charged in a 15-count federal indictment that alleges conspiracy to distribute and possess with intent to distribute 500 grams or more of methamphetamine.

Most face additional charges related to alleged drug and/or firearms offenses, the release states.
